ScreenBeam ECB6250K02 MoCA2.5 Network Adapter Starter Ki (Open Box)

Basic back ground. I am an IT professional, 24 years. The installation and configuration on a technical scale is childs play for me. I purchased 8 of these devices from November 2002 - April 2023 to install in my home network, despite having a robust WiFi mesh delivering 800+ link speeds to Ax devices. There are cases however, where I need to have physical connectivity since the 50+ endpoints in my network are not all Ax rated and the airspace is crowded. All Screenbeam MOCA devices initially worked as expected. As of June 2023, 5 of the devices now have defective Ethernet ports. Ethernet ports are a common failure point on routers, switches, and media conversion devices (like these). Bonding occurs as expected; however, Ethernet link activity and addressable network is non existent. That’s 5 failed devices out of 8. I requested an RMA under warranty through customer service. The response has been slow, but worse, the company customer service rep (unknowledgeable about IT networking 101) has asked for troubleshooting steps that are inconsistent with the issue. Also, have been instructed to perform time consuming phone calls with no clear understanding of the purpose other than to extend the support case. While understanding that I am allowing the company to proceed through their case management process to get an RMA (I get it, process), I performed the basic troubleshooting steps requested. Supplying results, I was told the devices were working as expected and asked to call customer service. This is a deliberate attempt to prevent or slow replacement - I know because I ran a consumer electronics call center long ago in my career (also the reason I left that job 15 years ago). This is ridiculous and a continued attempt not to issue the RMA and replace the devices under warranty. You can simple swap in a defective device to the topology, bonding occurs, and network traffic is non existent - no link activity on the port, no addressable network layer. Swap again with a good device and no issues. These devices have a 1 yr warranty. I share this experience so you can make your own judgements, but I cannot recommend these devices with high failure rates and when the company does not honor the warranty/RMA process. This is contractual. While most buyers/reviewers may purchase and never have an issue - providing 5 star reviews about the excitement that these devices “magically work”, I say proceed at your own risk. If these devices were $20-30 like a common desktop network switch, or 1-2 failed devices, I would just eat it and move on. But they are not. At $70 a pop, 5/8 device failures, we are venturing into material expense for a majority of people. I fundamentally do not accept this performance. I am moving on to competitor devices. Buyers be warned. Lastly - if Screenbeam customer service responds to this comment that they would like to “help me” - by directing me to call customer service, I say no thanks. Spare us the perception that your company is trying to resolve the issue when I already gave you that opportunity. Save me the intellectual dishonesty. The resolution is RMA. Period. The resolution is not to stay on the phone wasting my time teaching your low level techs basic networking and your continued assertion that the devices are working and the issue is my “other equipment”, WAN provider, or a coax splitter that isn’t present in the network topology. Comical.
